What is the value of x... 5(x-5)=3(x-7)

Mathematics

Answer:

x=2

Step-by-step explanation:

5(x-5)=3(x-7)

Distribute

5x-25 = 3x-21

subtract 3x from each side

5x-25-3x = 3x-21-3x

2x-25 = -21

Add 25 to each side

2x-25+25 = -21 +25

2x=4

Divide by 2

2x/2 =4/2

x=2

Answer:

Choice B: Only (-1,-5)

Step-by-step explanation:

With this one, first the equation needs to be reduced into point-slope format.

y+5=2(x+1)

Distributive Prop.

y+5=2x+2

Carry over the 5 to the opposite side.

y=2x-3

Now, with the point slope form, it makes it easier to plug in the question choices to find which if any are correct.

Choice A: X is 5; Y is 10

y=2x-3

y=2(5)-3

y=10-3

y=7

This does not give a y value of 10, so it is false.

Choice B: X is -1; Y is -5

y=2(x)-3

y=2(-1)-3

y= -2-3

y= -5

This does give a y value of -5, so it is true. Choices C and D are therefore false as well, since only Choice B works.

Math help ASAP easy points<br><br> What is the value of Z?<br><br> Enter your answer in the box.
Romashka [77]
<h3>Answer:  23</h3>

The three angles of any triangle always add to 180, so,

z+62+95 = 180

z+157 = 180

z+157-157 = 180-157 .... subtract 157 from both sides

z = 23

As a check,

z+62+95 = 23+62+95 = 180

so the answer is confirmed.
